Pediatric emergency physicians are experienced in the diagnosis and treatment of all types of emergencies in infants, children, teens, and young adults. They usually treat the following types of emergencies:
Solar irradiance. It's reasonable to assume that changes in the sun's energy output would cause the climate to change, since the sun is the fundamental source of energy that drives our climate system. Indeed, studies show that solar variability has played a role in past climate changes.
The human causes of climate change are some of the most important concepts to teach. 1  Human activities, particularly the combustion of fossil fuels, are altering the climate system. Human-driven changes in land use and land cover such as deforestation, urbanization, and shifts in vegetation patterns also alter the climate, resulting in changes to the reflectivity of the Earth surface (albedo), emissions from burning forests, urban heat island effects and changes in the natural water cycle.
